Abstract: 756,941. Adjusting radio apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 8, 1953 [Aug. 9, 1952], No. 12914/53. Class 40 (5). [Also in Group XIX] An indicator for use in radio receiving apparatus as described in Specification 756,940 comprises a disc 13 keyed upon a shaft 14 (rotation of which effects longitudinal movement of tuning pistons 4) and bearing a spiral path 16 which engages an indicator element 18 which is constrained to move in a fixed radial direction with respect to a shaft 5 connected directly to the tuner 1. Thus rotation of the shaft 14 with respect to the coaxial shaft 5, by rotation of a knob (not shown) attached to shaft 26, causes the disc 13 to move with respect to the indicator 18 which consequently moves in a radial direction to follow the spiral trace on the disc. The disc bears graduations indicating the wavelength to which the apparatus is tuned, this being visible through the rectangular frame of the indicator 18. In the arrangement shown, the trace 16 is in the form of a groove within which rests a projection from the indicator 18, although it may alternatively be in the form of a rib co-operating with an appropriately shaped member on the indicator 18. The tuner 1 forms part of a turret which is rotated by means of a knob 9 forming part of disc 8 having a plurality of indicia around its periphery and also comprising a cut-away portion 12 through which the indicator 18 is visible.
